...I remember seeing one 'vertical' set, in around 2000, in 'Anglia', somewhere on the GE main line I think (Bentley crossing?): This was I'm sure, owing unsurprisingly to road width/proximity of road-side buildings.

This is Margaretting Church Lane CCTV crossing on the GE main line which has four 'narrow' light clusters on one side of the crossing. The road lights mentioned at Three Horse Shoes No1 & No3 AHBs and at Bentley AHB are of this 'narrow' type.

The roadlights mentioned at Lincoln High Street crossing are shown on Google maps - Street view with five 'standard' roadlights.

Elmswell CCTV crossing has row of vertical lights on the 'offside' of each approach which are very much more unusual. This type of light was used on the Up side road approach because of limited visibility caused by an adjacent warehouse obstructing the view of the crossing.

The narrow wig wags in the second photo are quite rare and are used where clearances do not allow the normal wig wag They need special authorisation from DfT. The vertical (in third picture) wig-wag is unlawful and always has been.

The enforceability (apart from the obvious risk of physical enforcement by a train!) of lamps mounted vertically, where the flashing reds are above one another would be questionable, since the highway code shows them horizontal.

several crossings on the Isle of Man Steam railway are equipped with vertical wig wams resembling traffic lights.They also ensure the road barrier extends fully across the road or employ two barrier machines,On the Electric tramway AOCL s have wigwams and the crossings only employ Silec 59 treadles to operate the crossings

As well as the wig-wams there are the standard traffic road signs warning of level crossing ahead to advise motorists they are approaching a level crossing.An amendment to the Highway Code should be made.At one of the Isle of Man s level Crossing the road sign depicting the level crossing sign also had a traffic light in addition which when the vertical red lights were flashing displayed flashing yellows .The approach road was on a slight curve.

The Isle of Man has its own peculiar laws which tend to follow mainland practice a bit loosely and sometimes a few years behind. I don't know whether the Highway Code is considered applicable there or if they have some local variant. I wouldn't be at all surprised if their courts took a different view from ours as regards things like non-standard wig-wags.

DoT (or equivalent) can authorise non-compliant road signs on a site by site basis. Authority is granted under TSRGD (or equivalent in NI.)

The Highway Code doesn't pretend to cover all road signs, just the most common ones. While the illustrations in the Highway Code show a horizontal arrangement, the Isle of Man can presumably authorise other arrangements?

The Highway Code is not a legal document.It MAY quote certain Legislation.
